Electrical Cable Motion Study

Phillip Gyasi-Agyei

Good day, community,

Is it possible to model the movement of an electrical cable as the assembly moves? For example, the twisting and bending of a cable running along a robotic arm as the arm's links move. Similar to this YouTube video:

I'm, trying to model an electrical connector being pulled out of a socket through a pulley. Essentially, I want to know if Inspire can simulate flexible objects (vs non-rigid bodies).

Regards,

Phillip

Hi Phillip,

 

Hakan is correct in that this approach is commonly completed by using NLFE bodies.

There is an example in the Altair Community Exchange that shows a robotic spider with the NLFE bodies.

I feel it will correctly demonstrate the approach you are after.

Please find it at the link below:

Hope this helps!

You can do it with NLFE using the MotionView interface. Detailed information is available in the help.
